-/**
- * More convenient version of PollableQueue that handles iterating
- * over the batch and error handling.
- *
- * Constructed in "bypass" mode where items are processed directly
- * rather than put on the queue. This is important for the
- * PRE_INIT stage when Cluster is pumping CPG dispatch directly
- * before the poller has started.
- *
- * Calling start() starts the pollable queue and disabled bypass mode.
